Risk factors identified for HBV-HCV co-infection

For people with hepatitis C, co-infection with the hepatitis B virus is much less common than exposure, and having both illnesses is linked to factors such as age, gender and HIV status, according to a study published in the journal Hepatology. The study population consisted of 168,239 people. "Based on these findings, all patients with HCV exposure should be tested for HBV," researchers said.
